MAFS.912.S-ID.2.6.a.b.c Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. a. Fit the function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models. b. Informally assess the fit of a function by plotting and analyzing residuals. c. Fit a linear function for a scatter plot that suggests a linear association. MAFS.912.S-ID.3.7 Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.

In this topic, students learn to classify and interpret scatterplots. Students

also learn how to find the line of best fit using graphing technology.

5 Residuals and Residual Plots – Part 1

MAFS.912.S-ID.2.6.b Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. b. Informally assess the fit of a function by plotting and analyzing residuals.

This topic focuses on residuals and residual plots and how they are used

to determine whether a certain function is a good fit for a model.

6 Residuals and Residual Plots – Part 2

MAFS.912.S-ID.2.6.b Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. b. Informally assess the fit of a function by plotting and analyzing residuals.

This topic focuses on residuals and residual plots and how they are used

to determine whether a certain function is a good fit for the data.

7 Examining Correlation

MAFS.912.S-ID.2.6.c Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. c. Fit a linear function for a scatter plot that suggests a linear association. MAFS.912.S-ID.3.8 Compute (using technology) and interpret the correlation coefficient of a linear fit. MAFS.912.S-ID.3.9 Distinguish between correlation and causation.

This topic introduces the concept of correlation, the correlation

coefficient, and what "r" tells us about the type of linear relationship

between two variables. The topic also discusses the concept of

causation and how this is different than correlation.
